[Feature Request] JRVR - Black Bar - Shift Image

I have to switch my project back to 16:9 so that i can see the toolbar which is annoying.

right now, you need to use the option
Options > Video > Advanced > Aspect Ratio Correction > 1.78 output to xxx display
since this is a zone setting you may also need to use zoneswitch to be able to route scope content to this zone and 16:9 content to another zone (that doesn't have this enabled)
if you need to do this, you also need to create a custom field which derives the cropped AR so you have a simple way to detect the aspect ratio. To do this, I created a calculated data field using this expression
--- Code: ---formatnumber(math(math(listitem([Video Crop],2,x) - listitem([Video Crop],0,x)) / math(listitem([Video Crop],3,x) - listitem([Video Crop],1,x))),2)
--- End code ---
you must have run "detect black bars" for this to work and this rounds to 2 decimal places
if you call this field CropAR, a zoneswitch rule would then be something like
[=Compare([CropAR],>,2.3)]=1
in order to choose scope content
hopefully this moves into JRVR and becomes largely automated sooner rather than later

the approach is to use offline analysis to determine the location of black bars which means it will never be live in the way madvr does it (unless jrvr fundamentally changes approach), at present use of this info is manual (using the set aspect ratio UI option) but I believe the plan is to automate this & drive that via jrvr profiles.

Thanks Matt, I did see that. I guess I'm asking (hoping) for that fundamental approach change.
The static bar detection seems to be aimed at the use case where there's an ultrawide display which would benefit from having the image scaled to fit it better.
All I'm highlighting is that there's another use case, those of us that want to move the image within a 16:9 screen. Static bar detection doesn't solve for that case.

Knowing where the bars are is an important step for all of those functions, otherwise there can be no automatic change.
PS:
2.35:1 can never fill a 16:9 screen unless you are happy to lose some image on the sides. And if thats what you like, you can combine the future black bar detection with the "Crop" scaling mode, and it'll fill the screen just fine.
Conrad:
Thanks for the reply.
I'm not trying to zoom the image, I don't want anything cut off.
What I use the black bar detection to do is to move the 2.35:1 image to the bottom of the 16:9 screen. So I have one large bar at the top of the screen and the image is flush to the bottom of the screen. This is much, much less distracting than having black bars top and bottom, and still works really well with the change of aspect ratio in Nolan movies (and others
It's also easier to mask with a single masking panel at the top rather than having to have masking panels top and bottom.
Wull:
I'm also hoping for black bar detection. It's a must for me with variable aspect ratio films when using a 2.35:1 screen. Either that or a way to blank the image (Epson projectors cant do this). Until then I'll have to stick with madvr.
